(template-compiler) Quote empty parentheses as attribute value fails compilation

[ravijayaramappa]

Description

Attribute value of "{}" was previously not being treated as an expression value and hence passed compilation with out an error.

<template>
    <h1>Hello world!</h1>
    <div data-foo="{}"></div>
</template>

This change was introduced in this pr https://github.com/salesforce/lwc/pull/3376/files#diff-068f1f2f0aba9934781faf5a43f0a2eb38351062f092def1194e83c21cec689cR25

Steps to Reproduce

Use the markup provided with lwc v2.41.0 and it will throw a Ambiguous attribute value... error. Prior versions of lwc worked fine.
